Finding Nearby Standard Stars for Michelle Calibration

Finding Nearby Standard Stars for Michelle Calibration

Enter a target position below (format as in the OT, say
16:44:29.470 and 23:47:58.20 for RA and Dec respectively).
Also enter the length of the observation. The task will
return the names of the 10 closest stellar standards one
might use for photometric or low resolution spectroscopic
calibration for three positions: (1) the target position;
(2) same declination, right ascension less by half the
entered exposure time; and (3) same declination, right ascension
plus half the entered exposure time.

For example for a 2 hour exposure the task will look for
standards at RA 1 hour less and 1 hour more than the target
position as well as using the target position. Three sets
of potential standards are returned.
